CAR-DOOR LOCK.

SPECIFICATION forming part of Letters Patent No. 416,486, dated December 3, 1889.

Application filed July 25, 1889. Serial No. 318,617. (No model.)

To aZZ whom it may concern:

Be it known that I, HORACE E. NEWTON, a citizen of theUnited States of America, residing at Greeley Center, in the county of Greeley and State of Nebraska, have invented certain new and useful Improvements in Car- Door Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention has reference to car-door locks; and it consists in the improved construction hereinafter described and set forth, whereby a simple and effectively operating contrivance is devised that may be readily operated to effect the fastening of the door, and while in said engagement conveniently sealed.

In the accompan yin gdrawings, forming part of this specification, Figure 1 represents a portion of a car-door, showing my improved lock applied to the front thereof. Fig. 2 is v a vertical central section on the line or 00 of Fig. 1. Fig. 3 is a side view of the lock.

Upon the front of the door A, adjacent to one of the edges thereof, preferably the front one, is secured a fiat rectangular plate 13, which is secured to said door by means of pins .or bolts a, and rearwardly from said plate extends an integral hollow projection 19, which is downwardly inclined and occupies snugly a correspondinglyshaped opening therefor in the door. Upon the front side of said lock-plate is integrally formed a lug C, the upper portionof which is cut away to form a square open recess, the side walls of which are presented by the sides 0 of the upper portion of the lug.

The locking-pin D is of the form shown most clearly in Fig. 2, and consists of a front block portion d, having a perforated ear at the upper side for the attachment of a chain 6, designed to be connected by a staple or other means to the door-front, in order that said pin may hang in a convenient position when disengaged from the lock, and from the rear side of said block 01 integrally extends a downwardly-inclined bolt f, of an inclination corresponding in degree with that of the rear hollow projection of the lock-plate.

The side walls 0 are each provided with a horizontal slot 9, which are on a line with each other and are adapted to register with a corresponding slot 71, located in the block (1,

when the latter rests in the lug. Each of the slots g h is enlarged at its front end to form a circular opening 1'.

In operation, the door being moved to a closed position, the bolt of the securing-pin is inserted in the tubular projecting portion of the lock-plate and the entire securing-pin then forced in until the block portion of the same rests snugly within the recessed portion of the lug. While in this position a considerable part of the bolt will extend beyond the rear ofthe car-door, soas to engage an inclined opening formed in the door frame or jamb, and thus effectually prevent any move- 'of the slots 9 and h.

It will be obvious that by the arrangement of slots and circular openings any style or character of seal may be employed in connection with my improved lock, and that in some cases, when desirable, a soft-metal pin may be passed through the circular openings and its ends riveted on the side walls. If preferable, one of the walls 0 may be omitted, as the bottom and one side ofthe recess will ordinarily suffice to prevent rotation of the securing-pin in its bearings.

I claim The combination, in a car-door lock, of a lockin g-plate provided with an inclined opening, a lug formed integral on its front side and recessed to form bottom and sides, as described, and a pin provided with a square block to bear in said recessed portion and having arearwardly-inclined cylindrical bolt, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

HORACE E. NEXVTON.
